White Box Technologies announced the launch of WBT Weather Data for Energy Calculations, a web site providing instant Web access to typical year and historical year weather files for thousands of locations around the world created from recorded weather data going back as far as 30 years to as recent as the past week.  This website has been created by a long-time building energy modeler with several decades’ experience in processing weather data for use in building energy simulations.

For typical year data, this Web site features ASHRAE’s IWEC2 weather files for 3,012 international locations, as well as TMY3, CWEC2, and CZ2010 weather files for US, Canadian, and California locations, respectively.  IWEC2 weather files cost $35 each, the other sets are public data hosted with permission and are free.
For historical data, this Web site contains weather files from 2007 to 2012 for over 10,000 locations around the world, including over 1,500 in the US and 300 in Canada. Older weather files going back to 1980 are also available and can be be generated on request. The historical weather files have been processed by WBT and cost $50 each. A typical year weather file can also be produced on request for any location with 7 or more years of historical data.
All weather files are provided in two formats: *.BINM for use in DOE-2-derived programs and *.EPW for use in EnergyPlus-derived programs, including the DDY file. The IWEC2 files also contain an archival *.CSV format, and the historical files an archival *.FIN4 format.  Discount prices for large orders and subscriptions are also available.
